(REQ) Get rid of the gunboats

[OlegM]

Can SOMETHING be done about them annoying gunboats that are spawned as harbor defences all over the map? Those are modelled on some obscure Japanese river gunboats, that are:

a) ugly
b) unhistoric (used only in China), definitely NOT deep in the Pacific
c) harmless

I think that Japanese had like less than half a dozen of those anyway.

The game should have much MUCH more of Japanese subschasers - in fact patrol craft (PC) - and small minesweepers employed as harbor defences and even as convoy escorts. These were very numerous - in fact it's a pity we don't have more variants but the one for each (PC and MSW) in the game should suffice - and historicaly used in those roles. (Not to mention they look good too.)
